Previously, Crown Prince Mo had sent people to keep an eye on the Qiao Clan's main family. Hence, the Hidden Night Pavilion was aware that Qiao Dongbo and his people were the ones who had captured d Qiao Mu's mother.
That's why Qiao Mu received such a quick response to her message from the Hidden Night Pavilion, who informed her that it was Qiao Dongbo's doing.
However, before the crown prince could send people to rescue Qiao Mu's mother, his crown prince consort had already gone to attack the Qiao Clan's main family's residence directly.
When Crown Prince Mo finally received this news, he immediately jumped up from his seat, unable to think about reviewing the memorials anymore. He promptly tossed his red ink brush aside and ordered murderously, "Immediately call for Yu Xiu to lead 3000 Dragon Saliva Guards to the Qiao Clan's main family's residence."
